## Summary
Fixes#23492
Fixes front-component application variables returning their encrypted
at-rest value instead of their configured plaintext value.
Non-secret application variables (`isSecret: false`) are now decrypted
server-side before being injected into the front-component environment.
Secret variables remain excluded and are never decrypted or exposed to
the browser.
## Root cause
The front-component resolver filtered secret application variables
correctly, but forwarded the cached `encryptedValue` directly. As a
result, `getApplicationVariable()` returned an `enc:v2:...` envelope
rather than the configured value.
## Changes
- Decrypt recognized versioned envelopes for non-secret application
variables.
- Preserve empty and legacy/plain values unchanged for backwards
compatibility.
- Add `SecretEncryptionModule` to the front-component module.
- Add coverage for:
- decrypting public variables;
- retaining plaintext compatibility;
- excluding secret variables without attempting decryption.
